Point me in the direction

[bubblerboy64]

New FX impact ll. I have 700 slug liner “a” and varmint knocker 31 grain slugs. Can you suggest a velocity point which might work.

I understand to some extent the many variables but figured perhaps I can get a starting point 

suggestions and advice also appreciated.

880+ would be a good start.

Ok. Thanks

I tested them at various velocities ranging from 850fps up to 970fps and the best accuracy for me was around 925-930fps. Like you mentioned, there are many variables and guns are different but this was the range where they shot best for me. Good luck!

Thanks stoti I did some preliminary testing and I think you are about right. I mounted my scope with new FX no limit rings and set the reg back a little. Ken had it shooting HOT which it seemed to like for the heavy pellets.

I would encourage any one interested to go ahead and buy the impact. There are just a few simple precautions if you follow them the gun is easy to work on

1) don’t fire the gun with the cocking lever back. Just make sure the lever is forward as it should be when you chamber a pellet And when that is likely to happen is when you change a mag. The cocking lever has to be back to insert the mag. Soon as the mag is in close the lever (forward) and either fire the gun or put the safety on.

2) don’t adjust the hammer spring with the gun cocked

3) if you want to LOWER the reg pressure vent the gun as is described on several YouTube videos You can increase the reg pressure with the gun filled with air no problem Do not turn the reg adjustment screw in (clock wise) with it aired up. 

There is a lot on information on YouTube about this gun and lots more here on the forum. If you can read and follow rather simple instructions ( which means if you can basically tie your shoe laces ) you can own this gun.

GO FOR IT

I’ve changed liners dirt simple to do.

Watch the YouTube’s take a few notes and if I can do it most anyone can
